Jackson-Pratt drainage bulb

After emptying a Jackson-Pratt drainage bulb, how does the nurse reestablish negative pressure in the system?

A. Fill the bulb with sterile saline solution.

B. Place the bulb lower than the client’s body.

C. Open the valve and fill the bulb with air.

D. Compress the bulb and close the valve.

A Jackson-Pratt drain creates negative pressure when the bulb is compressed and the valve is closed. This causes fluid around the surgical site to flow into the drain.
